Answer:

40 children went on the cruise.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of adults on the cruise

y is the number of children on the cruise.

57 tickets were sold:

This means that x + y = 57, and since we want the number of children y, x = 57 - y

Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.

This means that:

22x + 10y = 774

Since x = 57 - y

22(57 - y) + 10y = 774

1254 - 22y + 10y = 774

12y = 480

y = \frac{480}{12}

y = 40

40 children went on the cruise.

Write an equation of the line that goes through the point (6, 12) and has a slope of 2 3 .
Degger [83]

Answer:

3y = 2x + 24

Step-by-step explanation:

The correct question is as follows;

Write an equation of the line that goes through the point (6, 12) and has a slope of 2/3

Solution

Here, we have a point and a slope, and we want to write the equation of the line

The method we shall use here is the point slope method

Mathematically, that will be;

y-y1 = m(x-x1)

(x1,y1) = (6,12)

m = 2/3

y-12 = 2/3(x-6)

3(y-12) = 2(x-6)

3y-36 = 2x - 12

3y = 2x -12 + 36

3y = 2x + 24
